JESSE S. TEED, OF MORAVIA, ASSIGNOR OF ONE-HALF TO \VILLIAM A. KIRBY, OFAUBURN, NEW YORKI WATER-:WHEEL.

SPECIFICATION forming part'of Letters Patent No. 361,556, dated April19, 1887.

Application filed April 8, 1886. Serial No.198,278. (No model.)

To aZZ whom it may concern:

Beit known that I, J ESSE S. TEED, a citizen of the United States,residing at Moravia, in the county of Cayuga and State of New York, haveinvented certain new and useful Improve ments in \Vater-Vheels; andI dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters and figures of referencemarked thereon, which form a part of this specification.

This invention relates to improvements in the construction ofwater-wheels, the nature of which will be hereinafter fully explained,and pointed out in the claim.

In the drawings, Figure l is a perspective of the casing employed by mefor my improvements. It is partially broken away to show the peripheryof the center wheel and the buckets fixed thereon. Fig. 2 is a sideelevation of the casing having the cap removed, so as to show theopening in the case, the rollerbearings, and the end of the shaft. Fig.3 is a vertical central cross-section of the case and wheel, showing amodified form of bucket on a reduced scale. Fig. 4 is a sideelevation-of the wheel, one-half of the casing being removed. Fig. 5 isa 1 perspective view of a bucket on an enlarged scale.

The casing is composed of the two end plates or halves, A A, snuglyjointed and bolted together. These halves are provided with centralopenings, A through which the shaft B.

passes, and their outer portions, A A are expanded and made concave orapproximately semicircular, as shown, so that when brought together theyform an approximately-cylindrical passage, A in which the buckets,hereinafter described, travel in the operation of the wheel. The casingthus made is narrow in its central portions, in which the body of thewheel works. Each end plate has lugs A cast or otherwise provided on theouter face, and arranged so as to provide radial channels or recesses A,for the reception of the blocks 0 O O, which carry anti-friction rollersB which support the shaft B. The casing has an exit-port, A and one ormore inlet-ports, A

The inlet port or ports will be explained more particularly hereinafterin their relation to the buckets.

The blocks 0 C may be bolted rigidly in place, but are preferablyadjustable, like the block (3, which has a slot, 0 in its shank and isadjusted by a set-screw, O, threaded into the removable caps D. In therevolution of the water-wheel water will be sprayed or thrown throughthe openings A onto therollers or other bearings B, and will keep thelatter perfectly lubricated, so that no other means for lubricating needbe provided. The water thus sprayed onto the bearings finds its way backinto the case through a small opening, E, near the inner periphery ofthe caps D. Instead of the roller-bearings B fixed bearing-blocks may besubstituted, as shown by dotted lines in Fig. 2; but the rollers arepreferred, as the friction and wear are less.

The cap D is of suitable size to provide space for the bearing-blocks OC. It is made so that it can be bolted to the casing, as shown, and isprovided with an opening to permit the end of the shaft B to passthrough, the latter being packed therein to preventthe exit of water oringress of air. On the outer end of the shaft a band-pulley, B, or othersuitable device may be secured. The set-screw O. is threaded on the cap,as shown. Only one cap D and one set of anti-friction rollers orbearings are shown in the drawings. It will be'understood thatcorresponding cap and rollers are arranged on the opposite side of thecase.

The wheel F is a thin plate or wheel with hub and rim of suitablematerial, which is keyed to the shaft B about midway between theparallel sides of the plates A A. Its periphery extends about flush withthe point where the side plates begin to expand to form the cylindricalportion A To the periphery of the wheel the buckets G are secured. Eachbucket G is provided with a shank, GK, which fits into a mortise, G inthe side of the wheel F, to which it is securely bolted. The closed endof the bucket is approximately semispherical, so that the water or powermedium impinging thereon will be deflected outward on all sides in asheet or spray. The bottoms G* and tops G of the buckets are oppositelyinclined or flared to permit the escape of the spray without causing anylost power or re;

tarding of the motive power. bottoms may be set at any angle to eachother and to the radii of the wheel; but the construct1on shown, andmore particularly hereinafter referred to, is preferred, and in practiceis found to give the best results.

In cross-section thebucket may have the sides 1n planes parallel withthe plane of the wheel, or said sides may be expanded and conformedsomewhat to the passage A*, as shown in Fig. 3. The principal feature towhich I call special attention is that of the bucket in its longitudinalsection, whereby the force of the jet of water is always received on therounded or inner closed end thereof. By reference to the drawlngsit'will be seen that the tops G and bottoms G are so arranged that eachstands approximately at a tangent to the periphery of the wheel. Thisrelative position is not so absolutely necessary for the bottom as forthe top. The bottom may be made to deflect from the tangent more orless; but the best results are attained when it is made so as to set onthe tangent line. The object in setting the bottom G on the tangent isto provide a free surface along which the water will be thrown afterstriking the closed or inner end of the bucket. If the bottom were seton the dotted llne G in Figs. 4 and 5, the free backward movement of thewater would be somewhat obstructed, producing a counter effect insteadof being utilized as power.

By my preferred construction the inner end of the bucket is alwaysclear, so thatthe force of the j et is unbroken by accumulated oreddying water. The greatest power that can be exerted by the momentum ofthe water is when the latter acts on a hinge or on a line parallel witha tangent to the wheel.

The top of my bucket is set approximately at a tangent to the wheel, sothat when its outer lip, G, passes the inlet-port the jet moves parallelto the inner surface thereof and strikes the inner end, as shown by thearrow marked J in Fig. 4. As the bucket is driven forward the jetretains its relative line with the wheel, while the closed end of thebucket is given new relative positions to the line of the jet, so thatthe latter is directed at all times against the inner end or bottom ofthe said bucket, as will be understood by reference to the arrows J andJ which indicate, respectively, the relative lines of the said jet inits first and last contact with the bucket.

Theprinciple on which my device is constructed and depends is theutilization of the percussive force of the water thrown in a straightline, which force is determined by the weight behind the chute or jet,or, in other words, by the number of pounds of pressure to the squareinch exerted by the body of water from which the jet is thrown. The jetpro- 7 jected against my bucket strikes thelatter with a force equal tothe pressure of the water.

These tops and The elliptical form of the'bucket permits the jet ofwater to be broken and disintegrated and thrown backward or outward fromthe bottom or hollow apex along the sides of the bucket in a spray.

The inlet-port A is arranged to throw the jet on atangent to the wheel,or on aline beyond .the periphery of the said wheel and parallel withthe tangent. vTwo or more inlets may be employed, if desired. Each inletis to be arranged, as described, for the single jet.

The wheel may be used equally well in a horizontal or vertical position.When arranged to work in a horizontal position, the shaft B must besupported in a vertical position, as willbe readily understood.

It will be observed that the shank G is set to one side of thelongitudinal center of the bucket, so that when the latter is secured inplace an equal portion of the bucket will come on each side of the planeof the wheel, as shown in Fig. 3. The mouth of the bucket inclinesrearwardly and upwardly, so that the edge of the top is set far back ofthe edge of the bottom, as most clearly shown in Figs. 4 and 5. By thisconstruction the buckets, when arranged upon the disk, have the rear endof one bucket overlapping the forward portion of the bottom of thepreceding bucket, and the jet of water will strike the inner end of eachbucket only, and will play upon the bucket next in order the moment itbegins to leave the bucket immediately in advance thereof, thusutilizing the force of the water tothe best possible advantage. Thewater as soon as it strikes the bottom of the bucket is deflectedoutward and backward, not against the sides of the casing to createfriction between it (the casing) and the wheel, nor yet back against theincoming water to retard its momentum, but in an outwardly andrearwardly direction, as previously intimated, that will permit it toescape without producing any lost motion.

Having thus described my invention,what I claim, and desire to secure byLetters Patent,

The combination, with the case and the wheel, of the buckets having theend of one bucket overlapping the bottom of the preceding bucket, eachof said buckets having the top and bottom oppositely inclined andtangentially arranged to the wheel, and having the end of the top setbeyond the end of the bottom, and having the sides substantiallyparallel and the inner endclosed and rounded, substantially as shown,and for the purpose described.

In testimony whereof I affix my signature in presence of two witnesses.
